Embodiment 1

[0023] Such as figure 1 As shown, the anti-wave device for an offshore working platform according to the embodiment of the present invention includes an airbag assembly 1 and a positioning assembly 2 for positioning the airbag assembly 1 on the platform structure. The airbag assembly 1 includes a plurality of Upper is the air bag 11 of elongated tube.

[0024] Such as figure 2 with image 3 As shown, the airbag 11 includes a hose 12 and connecting joints 13 arranged at both ends of the hose 12 , and the hose 12 and the connecting joint 13 are hermetically connected. The main body of the airbag 11 is a hose 12, the production process is simple, and even if the end part leaks, it can be easily repaired and maintained. In this embodiment, the hose 12 is formed by winding high-strength fiber filaments and primer materials, and the high-strength fiber filaments may be carbon fibers, glass fibers, aramid fibers or other high-strength fiber filaments. In addition, it can also be...

Embodiment 2

[0031] Such as Figure 5 with Image 6 As shown, the anti-wave device for the offshore working platform in the embodiment of the present invention is basically the same as the first embodiment, and the main differences are: the airbag 11 is spirally wound and sleeved on the platform structure; the positioning assembly 2 includes the airbag 11 There are the same number of restraining steel plate units, the restraining steel plate unit includes two restraining steel plates, one restraining steel plate is connected with the connecting joint 13 at one end of the air bag 11 , and the other restraining steel plate is connected with the connecting joint 13 at the other end of the air bag 11 .

[0032] In this embodiment, the airbag assembly 1 is provided with an airbag 11, and the positioning assembly 2 is provided with a constraining steel plate unit. In addition, a plurality of airbags 11 in a winding structure can also be used, and a plurality of constrained steel plate units can...

Abstract

The invention discloses a wave resisting device for an offshore operating platform. The device comprises an air sac component (1) and a positioning component (2) which is used for positioning the air sac component (1) on a platform structural piece, wherein the air sac component (1) comprises at least one long-pipe-shaped air sac (11) which is sleeved on the platform structural piece; the air sac(11) comprises a hose (12) and connecting joints (13) which are arranged at the two ends of the hose (12); and the hose (12) is connected with the connecting joints in a sealed manner(13). The wave resisting device for the offshore operating platform has the advantages of high sea wave buffering property and good protective effects on the offshore operating platform, is safe and reliable, is easyand convenient to use and is quickly maintained.

Description

technical field [0001] The invention relates to the field of offshore operation systems such as offshore oil extraction and gas extraction, and in particular to an anti-wave device for protecting an offshore working platform. Background technique [0002] With the depletion of oil and gas reserves in coastal areas and shallow water areas, the exploitation and production of oil and gas resources in deep water areas has become the goal of marine energy development. [0003] Most of the large offshore oil fields discovered so far are located in deep waters, and the exploitation and production of offshore oil and gas resources in countries all over the world are accelerating their development to deeper waters. The offshore working platform is one of the key structures in the deep sea oil and gas production system. However, due to the very large waves in the deep sea, the impact on the offshore working platform is very frequent. The beating and impact of sea waves on the structu...
